Several were listed by the MMS and maintained by the BOEM. SS Gulfoil (Built 1912, lost 1942-05-17), sunk by German submarine U-506 SS Gulfpenn (Built 1921, lost 1942-05-13), sunk by German submarine U-506 SS Robert E.

SS Amapala (Built 1924, lost 1942-05-16), sunk by German submarine U-507 The only known German U-boat to be sunk in the Gulf is U-166. After sinking the SS Robert E. Lee the United States Navy patrol craft PC-566 reported hitting and sinking the submarine. This was questioned and the sinking was attributed to a United States Coast Guard Grumman G-44 Widgeon, that reported an attack over 100 miles away, thought to be the U-166. In 2001 the wreckage of U-166 was identified near the wreckage of the Robert E. Lee and in 2014 the record was set straight that PC-566 actually sunk U-166. In 2014 the position, was designated a war grave.
